1Kernel driver abituguru
2=======================
3 4Supported chips:
5 * Abit uGuru revision 1 & 2 (Hardware Monitor part only)
6 Prefix: 'abituguru'
7 Addresses scanned: ISA 0x0E0
8 Datasheet: Not available, this driver is based on reverse engineering.
9 A "Datasheet" has been written based on the reverse engineering it
10 should be available in the same dir as this file under the name
11 abituguru-datasheet.
12 Note:
13 The uGuru is a microcontroller with onboard firmware which programs
14 it to behave as a hwmon IC. There are many different revisions of the
15 firmware and thus effectivly many different revisions of the uGuru.
16 Below is an incomplete list with which revisions are used for which
17 Motherboards:
18 uGuru 1.00 ~ 1.24 (AI7, KV8-MAX3, AN7) (1)
19 uGuru 2.0.0.0 ~ 2.0.4.2 (KV8-PRO)
20 uGuru 2.1.0.0 ~ 2.1.2.8 (AS8, AV8, AA8, AG8, AA8XE, AX8)
21 uGuru 2.2.0.0 ~ 2.2.0.6 (AA8 Fatal1ty)
22 uGuru 2.3.0.0 ~ 2.3.0.9 (AN8)
23 uGuru 3.0.0.0 ~ 3.0.x.x (AW8, AL8, AT8, NI8 SLI, AT8 32X, AN8 32X,
24 AW9D-MAX) (2)
25 1) For revisions 2 and 3 uGuru's the driver can autodetect the
26 sensortype (Volt or Temp) for bank1 sensors, for revision 1 uGuru's
27 this doesnot always work. For these uGuru's the autodection can
28 be overriden with the bank1_types module param. For all 3 known
29 revison 1 motherboards the correct use of this param is:
30 bank1_types=1,1,0,0,0,0,0,2,0,0,0,0,2,0,0,1
31 You may also need to specify the fan_sensors option for these boards
32 fan_sensors=5
33 2) There is a separate abituguru3 driver for these motherboards,
34 the abituguru (without the 3 !) driver will not work on these
35 motherboards (and visa versa)!

41 42 43Module Parameters
44-----------------
45 46* force: bool Force detection. Note this parameter only causes the
47 detection to be skipped, and thus the insmod to
48 succeed. If the uGuru can't be read the actual hwmon
49 driver will not load and thus no hwmon device will get
50 registered.
51* bank1_types: int[] Bank1 sensortype autodetection override:
52 -1 autodetect (default)
53 0 volt sensor
54 1 temp sensor
55 2 not connected
56* fan_sensors: int Tell the driver how many fan speed sensors there are
57 on your motherboard. Default: 0 (autodetect).
58* pwms: int Tell the driver how many fan speed controls (fan
59 pwms) your motherboard has. Default: 0 (autodetect).
60* verbose: int How verbose should the driver be? (0-3):
61 0 normal output
62 1 + verbose error reporting
63 2 + sensors type probing info (default)
64 3 + retryable error reporting
65 Default: 2 (the driver is still in the testing phase)
66 67Notice if you need any of the first three options above please insmod the
68driver with verbose set to 3 and mail me <j.w.r.degoede@hhs.nl> the output of:

70 71 72Description
73-----------
74 75This driver supports the hardware monitoring features of the first and
76second revision of the Abit uGuru chip found on Abit uGuru featuring
77motherboards (most modern Abit motherboards).
78 79The first and second revision of the uGuru chip in reality is a Winbond
80W83L950D in disguise (despite Abit claiming it is "a new microprocessor
81designed by the ABIT Engineers"). Unfortunately this doesn't help since the
82W83L950D is a generic microcontroller with a custom Abit application running
83on it.
84 85Despite Abit not releasing any information regarding the uGuru, Olle
86Sandberg <ollebull@gmail.com> has managed to reverse engineer the sensor part
87of the uGuru. Without his work this driver would not have been possible.
88 89Known Issues
90------------
91 92The voltage and frequency control parts of the Abit uGuru are not supported.
